15 Claims.

My invention relates to improvements in lineindicating copy holders wherein a pair' of similar, slidabiy superimposed sheets operate in conjunction with a line indicator movably superimposed upon one of said sheets and provided with means for engaging said sheets to permit movement of said indicator in one direction only, relatively to said sheets, whereby said indicator may be moved intermittently over copy upon said sheets when said sheets are intermittently reciprocated, one uponthe other.

The primary object of the present invention is to provide a new and improved line-indicating copy holder.

Another object is to provide a new and improved device of the character described which may be easily and economically constructed either from sheets of common pasteboard, to provide an extremely cheap device, or from sheets of a more '13 durable material, such as thin sheet metal or the like, to provide a more durable device, either material providing a device of extremely economical construction and having a maximum efllciency and ease of operation.

A further object is to provide, in combination with a device of the character set forth, an extremely simple, eihcient and easily operable device for regulating the amount of movement of a line indicator to equal single, double, or even triple spacing of a standard typewriter.

A still further object is to provide a new and improved line-indicating copy holder having many of the advantages and utilities of the expensive devices now in use, but one which may be produced at a greatly reduced cost and having a greater ease of operation.

A still further object is to provide a new and improved line-indicating copy holder that will be less bulky and lighter in weight than copy holders now in use, to permit a greater ease of transportation from one position to another, to promote a greater range of utility and a more universal use of copy holders. r

Referring to the drawings:

The numeral I is used to designate what I term, for convenience, a base sheet which may be formed of either common 'pasteboard or a more durable, thin sheet material, such, for instance, as sheet metal. The base sheet I is held, for conveniencein reading as well as for operation, slightly slanted or substantially upright by any suitable easel or support 2, as disclosed in Fig. 2 of. the drawings.

The base sheet I is provided with verticall disposed slots 3, a horizontal slot 4 near the base thereof, notches 6 in both side edges thereof,,and a tab I for engaging the easel or support 20 2, to retain said base sheet in a slightly slanted or substantially-upright position.

What I term, for convenience, a copy sheet 8, for holding copy 9, is slidabiy superimposed for limited vertical reciprocating movement upon the base sheet I and is also formed of common pasteboard or thin sheet metal, and is provided with notches 6 and with means for slidabiy engaging the slots 3 of the base sheet I, to limit reciprocal movement of said sheet 8 upon said base sheet I, 30 said means comprising either ordinary, brass paper fasteners II, as disclosed in detail in Fig. 3 of the drawings, or struck up lugs or tabs I2, as disclosed in full lines in Fig. 8 of the drawings, or any other suitable device by means of which said copy sheet 8 may be slidabiy super imposed for limited reciprocal movement upon. the base sheet I.

The copy sheet] is provided at its lower edge with a ledge or shelf it upon which rests the lower edge of the copy 8, this ledge also serving as a means of operation, as hereinafter more fully set forth.

' A line indicator I6, also cut from flat or sheet 45 material, is horizontally and movably superimposed upon the copy sheet I and is provided with a longitudinally disposed slot l1, through which the line to be copied, not shown, on the copy 9, is exposed, the longer edges of said slot I! being continued beyond the vertical edges of sheet 8 to form inwardly projecting tabs Il. The slot I1 is substantially the same length as the width of the sheets I and Q so that the inner ends of said tabs I8 form guides for engaging the edges of drawings.

of the indicator it proper engaging the front surface of the copy sheet 8, while the detents l9 upon the tabs [8 engage the back or oppositesurface of the base sheet I, to prevent upward movement of said indicator l8 relatively to said sheets, as disclosed in detail in Fig, of the draw ings, i

' When the device is made ofpasteboard the detents will effectively engage said sheets I and 8 and prevent upward movement of theindicator i6 thereon while readily permitting a downward movement of said indicator. 8 If it isdesired, the

detents l9, l8 may be slightly offset from each other in their downward paths so that. when said indicator has reached its lowermost position-and is resting upon the ledge or shoulder ll of the copy sheet 8, the detents I8 will register with the lower registering notches" 8 of .the sheets I and 8, to readily permit the detents l8 to disengage the back of the base sheet I.

When the device is made of sheet metal not effectively engaged by said detents l9, l8, suit-' able apertures 2|, arranged at spaced intervals equal to the standard spacing of typewriters, may be provided parallel to both edges of both sheets land 8, as shown in section in Fig. 9, of the The detents l9, ls'o will then intermittently engage successive apertures! instead of merely engaging the surfacesof their respective sheets, whenv the indicator i6 is moved downwardly as hereinafterdescribed.

A .plate 22 'is bent upwardly from a slide 23 resting upon thebase of the easel or holder 2 and has an integrally formed tab 24 slidably engaging the horizontal slot I in the lower portion of thebase sheet I, as disclosed in Figs. 1, 2, and of the drawings; to limit'movement of said plate 22. The plate 22 is interposed between the lower ends of the sheets I and 8 and is provided with an aperture 26 through'which the lower fastener II or tab i2, as thecase maybe, extends before passing through the lower slot 3 of the base sheet I. 8

The lower edge of theaperture 28 intercepts the lower edge of the fastener H1, or tab 12, when the sheet ,8 is moved downwardly-and limits such downward movement, which is equivalent to double spacing upon a, typewriter. I The aperture 26 is provided with a shoulder 21 which, when the slide23 is moved to the proper extreme position, intercepts the fastener H, or tab l2, whenthe same has moved a distance equal to a single space upon a typewriter. By means of this slide, the copy sheet 8 and indicator it may be moved for either single or double spacing, according to the nature of the matterbeing copied, suitable indiciabeing provided as at 28 toindicate for which, single or double spacing, the adjus table device is set. v

Whenv the device is made of pasteboard an ordinary elastic'rubber band 3i is stretched pref erably between the lower fastener l I, or tab I2, and the tab 'lflupon. the back of the base sheet I, as disclosed in 2 of the .drawings, in full lines,,and indicated in, dotted lines in Fig. 1.

This elastic rubber band 3| normally retains the'copy sheet 8 in its uppermost position upon the base sheet I and instantly returns said sheet to such position after having been moved downwardly and released.

When the device is made of a heavier and more durable material, such as sheet metal or the like,

a suitable spring, not shown, or stronger and larger elastic bands may be substituted for the ordinary rubber band shown, in order to more promptly return the heavier copy sheet to its upper. v position. p

In operationi f The copy 9 is placed upon the copy sheet 8 with the lower edge of said copy 9 resting upon and supported by the ledge l4 upon the lower end of the copysheet 8, as disclosed in Fig. 1 of the drawings, with the upper corners of said copy 9'inserted through inclined slots 32, in order to prevent said copy 9 from moving laterally and interfering with the path of progress of the detents l9 engaging the face of the copy sheet 8. The indicator I8 is then superimposed upon the copysheet 8 andover the copy 9 thereon nearthe top of saidsheet8 as disclosed in dottedlines in Fig. 1 of the drawings. This will place the detents i8', projecting from the inner ends of the tabs l8, directly opposite the upper registering notches 8 of the aligned sheets 'I and 8 so that when said tabs l8 are sprung backwardly beyond the plane of the indicator I6, and said indicator is moved to bring said detents l9 below said notches 6, and the pressure. on the tabs I8 is then released, the slight tension of saidtabs I8 will move the detents i9, I9'.,into engaging re? lation withthe front of the copy sheet 8 and the back of the base sheet I, respectively, and normally prevent movement of the indicator IS in either direction and positively in anupwardly direction, by reason of the'upward inclination of said detents l9, i9. When the'deviceis formed of metal theindlcator I8 is moved as above de'scribeduntil the detents l9, Ill engage their respective apertures 2| whichserve as rack teeth; in promoting the v downward progress of the indicator I5.

The indicator I8 is ,now' moved downwardly overthe copy 9" until the first line thereon to be copied is exposed through the slot l'l. After said line has been copied a slight downward pressure on. the ledge or shelf I4 will move the copy sheet 8 downwardly, against the tension of the elastic rubber band '31 until the lower edge of the fastener i l or tab l2, engages the lower edge of the aperture 26 in the member22 interposed between the sheets I and; 8, or the shoulder 21 of said aperture, and limits or prevents further downward movement of said sheet 8, During this downward movement of said copy sheet 8 the said-sheet is engaged by the upwardly slanted barbs or detents i9 and the indicator l6 ismoved downwardly an equal distance with said copy sheet/8, which distance is equal to a single or double typewriter space,'and'exposes through the longitudinal slot-l1 the 'next lower lineon the copy 8. I

When the pressure on the ledge or shelf H is removed the tension of the elastic band 3| will instantly return the copy sheet 8 to its uppermost position, as limited by the length of the slots 3, and during-this movement thev detents I8 will engage the back of the base sheet Land prevent a return ofthe indicator I 8, with said return movement of the copy sheetB,

This process is repeated after each line has been exposed through the slot I1 and copied, until the lower edgeof the,indicator l6 rests nil upon the shelf or ledge ll of the sheet I, in which position the detents I 9' will register with the lower registering notches 6 so that said indicator mayibe removed, the copy' 9 removed, and the process repeated with thenext sheet to be copied. The detents l9, [9, when the device is formed of pasteboard, may be of any suitable material sufficiently hard and sharp to eflfectively engage the',surfaces of .the sheets I and 8 and normally prevent movement of. the indicator l6.
